can anybody tell the clarification of variation of consecutive increasing and decreasing trend of coercive field with doping concentration. is it due to variation of grain size? or oxygen vacancies?
Vinay Sharma
Mr Babu please elaborate that what kind of materials you are using and also specify the dopants otherwise .....the main reason of change in coercive field is the oxygen vacancies generated due to doping because grain size doesn't change much but the lattice parameters change due to dopants which may leads to the change in magnetisation................................
